PSU - Which one to pick?

[Hi P]

I'm going to buy a PSU from a store near me, since I'm trying to buy as few parts as possible online.

 

I used the PSU Tier List to guide myself and I found 4 good ones, I think.

 

- They all are Tier 1 on the list

- Fully Modular

 

(Click to see them on Newegg)

 

- Cooler Master V850

- Corsair RM850X

- Corsair RM850i

- Corsair HX850

 

1.- Which one is the best in terms of reliability and features?

 

2.- Which of those two brands has better customer support?

 

3.- Which PSU would you pick and why?

 

It's 850W as I plan to have dual GPUs in the future, please help me and thank you!

Which one is the best in terms of reliability and features?

honestly they are all good.

 Which of those two brands has better customer support?

corsair imo

 

Which PSU would you pick and why?

 

what's your budget? the rM850 is the best valuu

EVGA's 850 G2 or P2 or T2 are all good as well.

1. They all have very similar features, but the Corsair RM850i has corsair link, which some people find helpful.

2. I would say that they have equal customer support from my experiences with both companies.

3. If I wanted the highest efficiency, I would go with the Corsair HX850, as its 80+ platinum. If I just wanted a PSU, I'd go with whatever was the cheapest corsair option which can power everything I need, which in this case, would be the RM850X, which as a bonus also has braided cables.

Hope this helps

Yeah I wanted the EVGA G2 but the store doesn't have it, only those 4

 

And price doesn't matter, they are near same price on the store

That was really helpful

 

1.- What's Corsair Link?

2.- Are Platinum PSUs generally quieter than Gold?

3.- Aside from efficiency, any bonus of a Plat over Gold?

4.- What's braided cables?

Corsair link is software that can be used in order to monitor different attributes of your PSU, such as its temperature, fan rpm and power consumption. Also Platinum PSU's arent really any quieter, they just provide a higher efficiency, which can mean less heat output, but not anything noticeable. Braided cables are cables that have been covered with a fabric looking material in order to make them look nicer overall, so instead of seeing rubber, you see something which looks like fabric (Not the best description, but covers what they are)

Those PSU's are all good but I'd go with a Corsair PSU. EVGA's G2 and G3 PSU's would also be a great 80+ Gold option.

[Hi P]

@Meag Thanks a lot

 

Last two questions (if you don't mind)

 

1.- Are all of them "SLI ready"? since Newegg only lists the RM850i as SLI ready and blank for the other two (talking about the corsairs)

 

2.- When people say "don't cheap out on PSU" does that include efficiency? because I could either buy the Platinum PSU or go for the RM850X and save a bit.

The G2 is on Amazon for $100

1. They all will be 'SLI' ready. That's just good marketing on the RM850i. All those PSU's have support for 4 VGA power connectors which is all you would need.

 

2. The 80+ gold PSU's you are looking at are Tier 1 PSU's, don't make the mistake of associating efficiency with quality. You can spend more on an 80+ platinum PSU and it's a lower build quality than an 80+ Gold PSU. The difference mostly is efficiency, so an 80+ platinum PSU will be more efficient meaning it won't draw as much power as a lower rated PSU with the same power load. It's up to you if you want to get a platinum PSU but make sure it's built well and is a Tier 1 option. Buying a platinum rated PSU only to move down to a Tier 2 or 3 PSU is a poor decision in my opinion. Efficiency doesn't equal quality.

All of the power supplies will work just fine with SLI, they all have the same wattage and offer the same amount of PCI-E connectors. When people say "Don't cheap out" they mean buying a low tier power-supply, such as one with no efficiency rating or from an unknown brand. A gold rating or platinum rating is defiantly not cheaping out assuming the quality of the powersupply is good, but you already have seen they are all tier 1 rated.

Correct but again efficiency doesn't equal quality. There are plenty of crapy Gold and Platinum rated PSU's on the market.

I did say that a gold or platinum efficiency PSU is good if the quality is good in terms of not "Cheaping out", I however, never mentioned that if its good efficiency then its high quality. Also in this case that isn't really important, as they are all Tier 1 power supplies, so they are of a similar quality for this comparison

yeah but that doesn't solve any questions my dude,

 

chances are, he has already come to that conclusion given they are all "tier 1"

Reliability: I'd say the RM850i given it's the only one you mentioned that does support multi-rail mode.

 

In therms of features the RM850i also comes with corsair link, a software that allows you to monitor and control your PSU. as far as corsair goes RMx and HX don't support corsair link.

you shouldn't care about the brand much. Everyone has had good/bad experiences with certain brands and that makes them assume they're always going to get the same treatment.

3.- Which PSU would you pick and why?

 

I'd go HXi or AXi if I could, a bit more efficient than RMi but still has multi-rail mode.

If not there's the dark power pro which does do multi-rail but doesn't come with any kind of software.

And there are some titanium units but non of them has multi-rail IIRC.

Never heard about this, what is multi-rail mode?

and please no more please help titles

 

just write down your main question or problem like "don't know what PSU to pick" that's what titles are for.

[Hi P]

@17030644 Ohhh, okay I'm not taking my chances, from the four PSU I listed is the RM850i the only multi-rail?

 

P.S: Edited title

yeah, any corsair with the i at the end enables you to decide if you want to use the single or multi-rail mode.

 

In many cases you can even configure the OCP triggering point

[17030644]

you can tell a PSU has multi-rail mode by looking at the power label most of the time,

 

except with those corsair and nzxt ones, because they can also act as a single-rail PSU if you want it to.

[Hi P]

@17030644 A bit of an out of topic question, but do I need another device as Power Regulator (something like that) or not really?

It'd be nice, but It's better to have an appropiate electrical installation I think

 

the PSUs themselves have a MOV/TVS diode that protects agains voltage spikes coming from the power grid.

Still doesn't solve anything. It's useless

 

At least say "get this one" or "get that one" saying all of them are equally good looks as if you hadn't said anything.
