I think my power supply may need upgrading now =/

post #1 of 12
Thread Starter 
It works fine, but I ran out of connections on it for everything and there's no more open spots for the new SSD and 2tb hard drive I just bought. Also, only 3 of my case fans are working and they're all plugged in. You think a 520w psu is finally not able to handle the rig since I upgraded everything on it?

If so, recommend a decent cheap power supply for me. I'd like a fully modular if possible as this one is modular except for the big wad of cables for the motherboard connections.

My needs are:

6 hard drives (4 hard, 2 ssd)
1 graphics card that requires 2 6 pin connectors
6 case fans (they've got the mini connectors, not the 4 pin molex, the smaller ones)

I really don't know what I want to spend, but I really don't like to gimp the power supply, but as cheap as I can get.

Just use some cable splitters and adapters. It's not like you're pushing that close to 520W.

This is a good price on an OCZ ZT 550W (fully modular) though, which is a decent power supply:

I'll go get a few splitters then. And will my power supply handle possibly 2x 580s in the future or no?

There's a 750W version of this one. I have the Hive 650 and it's actually very nice. Very quiet and cool. $89.99 before $15 off with promo code.

And the internals are the same as the OCZ ZS (same psu different label) with the difference being the rosewill is modular.

Keep us updated on what you pick.

If you are really considering sli 580s then you should look into atleast a quality 750W unit. Since You Fold@Home, you should probably get atleast an 850W unit with sli 580s.
The official OCN psu calc: http://www.overclock.net/t/1140534/psu-calc-final-release

With your current rig you can stay with the 520W and just get adapters as mikeaj suggested.

I would reference the suggested psu sticky to look into good 850 watt solutions if that is what you decide to do. There are some very good power supplies available. XFX, Seasonic, Corsair, Kingwin, NZXT, Antec, Rosewill, Sentey etc. all have good units. It is important to look into reviews for the particular model you are looking at buying, as each Brand has a range of products which vary in quality.

I agree and I can't stress enough to read the reviews on hardware secrets. I've seen a lot of reviews which really don't push the psu to see it's failure point (the uncovered one psu that had been given multiple "gold" awards by various sites that can actually catch fire because the stated "overvoltage/overcurrent" protection was nonexistent not to mention it didn't even meet the stated specifications the manufacturer posted for constant W or max).

No. I run a pretty good 750w with mine, and a good 750w will do it. However, I'd get an 850w if I was you, Will run cooler, perhaps less noise, and more so in an efficiency sweetspot. The Capstone 750 for $110 would be fine for you though I'm sure..

Here are some splitters though:

PWM Splitter
Molex to Sata Splitter

Modular Gold & Silver Class:

Kingwin Lazer Gold 850w $155
Rosewill Lightning 800w $156
Corsair AX850 $165 Shipped. $145 after MIR.
XFX PRO850W XXX Edition $167 Shipped. $147 after MIR.

Bronze Class:

Corsair TX850v2 $115. $100 after MIR. (non-modular)
NZXT HALE82 850w $146 Shipped. $116 after MIR.



The Winner here is the AX850 in terms of price/being one of the best PSU's out there.
