Safe way to adapt a 4 pin CPU to an 8 pin?

Maybe look at the used market?

2650v2 performs very similar to newer CPUs like the 6700k, I've got 32gb of ddr3 in quad channel running at 1866 so it performs about the same as dual channel ddr4 at 2133, people have easily got the 2650v2 running at 4.2ghz on all cores consuming around 140/150w at load, don't really want to upgrade the entire system when what I currently have still runs everything fine and has newer features like an nvme gen 3 so there's no need to really spend the extra yet, I bought the system about 3 months ago and the entire build came to less than £180 here in the uk so it's pretty good value in my opinion

That 2560 OC depends on more factors. Cooling solution, stability of the current supply from the psu (it is not a rule, but PSUs that come with an 8 pin connector OOTB, on average tend to provide a more stable power, it may mean they didn't try to skimp out on too much). It might depend on the quality of power delivery of the motherboard. It can depend on the quality of the ram a little. Big current draw on the gpu can affect system stability on such a limited PSU if you OC the CPU. Even the bios has some say in the matter.

 

And you should not really compare a considerable OC you may or may not get on a CPU you don't yet have (you said you will be moving to a 2560v2) to the boost clock of another that has a different IPC, different process node, different memory, different voltage range.

 

Also, what motherboard are you using? Hard to believe you could get a Z series board included on that bundle.

 

Finally, that i7 and it's younger brother, the 7700k pretty much qualify as i3s or R3s these days. Nobody is saying you should move to newer platforms, or that most games need it, but do not kid yourself regarding the performance tier of the CPU you have and the one you are moving to.

if you got your build to work with a psu harvested from a prebuilt, good on you.

 

if you want to overclock with said power supply, already aware that it's not built for the task you're intending to use it for.. GET A DECENT FREAKING POWER SUPPLY.

 

rated wattage is one thing, connectors is another. the thing about rated wattage is, if your power supply only has a 4-pin cpu power connector, it is not designed to handle anything more than 150 watts to the cpu. most enthousiast marketed power supplies (you know, the ones on the shelf with a fancy box) are built to handle people pushing the limits. power supplies in prebuilts very much arent. a power supply in a prebuilt is built to last a decade, and do so as cheaply as possible, because that's the market of prebuilts: hitting a pricepoint, and low RMA rates.

 

also, if you're talking overclocking, the stability of the +12v rail is a notably important factor, and if you're pushing an underrated connector, you are basicly just asking for instability.

What brands or models of PSU do you recommend, looking at even the cheapest new psus and they are costing over a 1/4 of my whole build, around £50 for an evga 430w psu

Brands? ADATA, because they only have one PSU. If I tell you EVGA or Corsair then you will look at the cheapest PoS unit you can get, like that 430w you're looking at.

That 430w was still £50 and was an 80 plus silver

I'm not kidding myself on the performance, my mate has a 6700k and gaming was identical at my stock speeds on some games, other games that favor fast cores clearly won because my current CPU is running at 2.3ghz

 

Motherboard is a Chinese x79

Not sure, would you recommend going used?

I know the type of board category you speak of. Heard about them even before LTT mentioned them in their videos. I do not trust the power delivery on those boards to do any real overclocking. And BIOS settings are lackluster on those boards. And they use newer either recycled or maybe even rejected PCH chips, in order to support nvme and stuff.

 

"Some games" are not a good benchmark of the overall performance of the CPU. Usually it is the newer types of games that are the target, or popular esports titles. For example, i can play Hearthstone just fine on an old pc i have in a vacation home that has a q6600 and a 5570. I have yet to even try to run stuff like the Witcher 3 on that thing. I would not say that it qualifies as anywhere near the performance of my partner's 3770 or my 7700k.

 

Me, and other people are saying that investing in a quality power supply that can probably also power a future build makes more sense than adding 4 more threads to an already low frequency CPU. Because, after a certain threshold, IPC and frequency are more important for gaming than thread count, just as, after a threshold, that is less i.portant thn gpu performance. Not sure it is aplicable to gaming, but there are cases where new instruction sets or hardware acceleration for some tasks has a bigger impact on overall performance (things like nvenc, or quicksync, if it is still used)

 

Unless you can get that 2560v2 for 10-20$ or get it for free or are specifically upgrading a server, the money for it are better spent on a bigger ssd, or moving to one if you never had one, or going to a more stable power supply.

 

People are not trying to power supply or platform shame you. You should save that money for future builds, or save it in this likely failing economy, considering the times, or invest it in a component that matters more for the day-to-day stability or performance of your system.

I don't think so and there are no silver Evga units out there, but correct me if i'm wrong. Anyway, the Be Quiet on ebay isnt better either.

False. Games are starting to use even more threads. after console release game are starting to use aroun 16 threads

So what am I supposed to be looking for? My budget is limited so I don't have the £100 people are saying

Well it depends on your budget. For around £50-55, you could get a 500w beQuiet! System Power 9 which would be a hell of a lot safer. Or save £10 by getting the 400w version. Either way, you won't get much cheaper without going to the used market

Is used a good option? Because I don't want to have to upgrade next year

Depends on your budget and what you are planning on doing in the next year. If you are just going to use a lower power-drawing GPU, like the 570, and you aren't going to go over 300-350w, you could get a used PSU that at least has some quality instead of the Chinese brands with fake wattages.

 

I don't know about your second-hand market (I'm American), but if you can find the System Power 9 or something of similar quality used for around 30-35 pounds, you should be good even if you upgraded the rest of your system, though if you want a high-end GPU (like a 2080), it would be better to buy a new PSU both for the warranty and piece of mind that you won't have someone else's PSU that could be fucked up in some way.

What IS your budget exactly? Hard for us to actually recommend anything when we don't know what you are willing to spend?

Thought I mentioned it? As low as possible, don't mind paying around £30-£40 for one

Was maybe planning a rig upgrade later down the line to x99 based system when the prices of boards drop a little more hopefully
