Is 500Watt enough?

[Brian Furious]

Hello guys. I was wondering if I can use my old 500Watt CoolerMaster PSU for:

 

Intel Core i7 6700k (won't OC with this PSU at all)

16GB RAM ddr4 3000Mhz

nVIDIA GTX 1070 Asus Strix

1 SSD

1 HDD

 

I have done a theorical calculation and it's about 380Watt and reccomanded a 460Watt. Will it be safe to have the PSU cause I wouldn't affroad another PSU.

[thebrownieguy]

Depends on the brand/quality but you should be fine.

[Godlygamer23]

What power supply exactly?

[bgibbz]

the wattage should be fine. What is the exact model number of the psu? I would hate for you to destroy your hardware because of a low quality psu.

That system will breach 300W only if overclocked. What 500W Cooler Master unit is it? They have some super shitty units.

[Enderman]

Yes, 500W is enough, but you should use a PSU from a reliable brand like EVGA or seasonic.

Then you don't risk a housefire from a cheap CM PSU.

[CostcoSamples]

How old is it? They lose capacity over time. If more than 5 years, toss it in the trash.

[Brian Furious]

As last replier mention it has about 6 years of life. As I look on the PSU the Product NO. is RS-500-PSAP-J3, it must be a cheap chinese PSU. It also says that the +3.3V & 5V & + 12V shall not go over 427.9W . So it is basically a 420Watt PSU.

 

With a 6 years old PSU, and basically a 420Watt should I keep it?

[Light-Yagami]

No. It's not. I have the exact same components in my computer and power usage howers around 400-450 wats at load. That is too much for 500W PSU. I'd say at least 550W, so you always have at least 100W more than you can draw. If you calculate on the cooler master site or sth, you will get around 380W total power draw, but in real live with all the devices runing and everything it's higher. If i were you, i'd get a 600W. But a 550W will do as well. Cheers

 

P.S. remember the efficiency curve of a PSU. the best is around 70/80% usage.

Alright then. I don't even think it has 80 bronze certificate at least. I'll get a CX 600 for 50 bucks then

The PSU you currently have a can confidently call garbage and really needs to be upgraded. That said 500W is more than enough.

The CX 600W is not a fantastic PSU and I wouldn't recommend that you get that one in particular, but it is still very much an upgrade.

Get an EVGA G2, B2, GS, GQ, anything from Seasonic or XFX (excluding the XT), Corsair RM, RMi/RMx/HXi, Vengeance, CX450/550/650M instead.

Well I know many good quality PSUs as well. That would be my new friend's PC. Personally I have a Corsair CX600 V2 for 4 years and never had problem with it. The max underload peak that I had is 300Watt. You just mentioned pretty much all the 80 gold certificate PSUs which are expensive af  .I would like also to get a modular (no semi! ) because I want to save space, better airflow, and cables replacement. My PSU has a broken V12 rail to a wire which became black, I think it was about to burn, so I just have settled by myself and it is working just fine. Now from a €1000 budget PC I think I'd have to cut off some part like the CPU or maybe getting a SSD later on.

The CX V2 is not great, the efficiency rating is not all what makes a good PSU, example the CX 400W is quite good and it is has an 80+ White efficiency. The CX 430/500/600 are just a based on a mid tier PSU platform and not designed for a gaming GPU.

 

If you are looking for a cheaper but very good PSU, the XFX TS, Corsair CX 450/550/650, Corsair Vengeance, Antec High Current Gamer and EVGA B2 are very good options.

Just an FYI, the CXv2 did have reported primary cap failure, which cause Corsair to address it in the v3 / Mv1 model. While the CX600M can power your setup, it's a bit obsolete and of poor value. Look into getting the newer CX450M / 550M for your system or the Corsair Vengeance 550M which is a better build version of the new CX model.

Yup, but make sure it's a non-exploding model, you wouldn't want the Note 7 of PSUs

well thats a new meme.

I was wondering why my CX600 has 2x PCIE power connectors if it wasn't for gaming properly. We speak back in the days in 2012 when I bought it and since then I am sure there are much better PSUs than this, but let's face it my i3 4130 and GTX 760 is just enough for this PSU that I bought long time ago. However here the problem is that I have another cheap one that needed for a new build. (no I can't use this PSU in the new build since it's not mine ) . However I don't think that is better low Wattage rated golden rather than a higher wattage bronze which I think is just enough. Like 550Watt 80 gold rather than a 750 80 bronze at the same price

When I bought the CX v2 the v3 did not even exist

I'm aware that the the v3 may not have been existed yet when you bought the v2. My point was that just because something works never give you any noticeable problems within the time span you had owned, that shouldn't give you the reason to continue to used or buy another PSU without any concern for its quality.

 

I have dealt with people who own PoS power supplies that seemingly power their system just "fine" and wonder why the certain components had died multiples of times within a year or two due to poor DC output quality - not all power supplies goes out in a bang. Of course, the CXv2 wasn't that bad; however, since you are buying a new power supply, especially one to power a new $400+ GPU, putting some money into getting a proper, modern day PSU for your system is well worth the investment.

 

Also, the 550w Gold vs 750w Bronze point. It's a matter of which specific unit we are talking about. There are 750w power supplies that goes out of specs at ~550wDC, in which case, I have no problem buying a quality 550w Gold unit like the Seasonic G 550w over it. Of course, that doesn't mean I would get the FSP Aurum 550 Gold over the EVGA Supernova 750 B2.

 

Anyways, if you want something inexpensive, the new CX450M / 550M / 650M are some good, modern budget options which should be in the same price point as the CX430 / 500 / 600 / M.

Alright thanks
