Another PSU size consultation... 1250W vs. 1500W

benny d. · 10-08-10, 12:38 PM

Hello all,
I currently have a Enermax Galaxy-S 1250W PSU in hand and am even considering the Silverstone Strider 1500W unless this is heavily advised against...
Here's what I'm driving folk's:

Intel i7 980x (OC to >4GHz range)
Asus ROG Rampage III Extreme
Asus ROG Matrix 5870 Platinum x2 in CrossFire (OC to >1000MHz range)
Corsair Dominator 1600MHz CAS7 6x2GB (OC to >1900MHz range) + fans
Corsair Hydro Series H70
Crucial C300 128GB x3 [RAID0x2 + OSx1]
LG Blu-Ray/DVD+RW
Thermaltake Level 10 case fans off of MB:[140mmx1/120mmx2/80mmx2]

That's everything, so, given the Matrix 5870's have been seen around ~525W a piece OC'ed under load, the CPU around ~200W, not to mention the memory + SSD's + MB's + cooling's load (and fans) on the PSU while trying to stay at a good efficency, doesn't the 1500W seem like the better bet...? Anyone per chance know if the Silverstone beast will fit well in the Level 10 (it's apparently 10mm too long)...?

Thanks in advance for the info people!

525w each? That doesn't seem right

Where in creation did you get those numbers that matrix 5870's can hit 525W a piece? Wow. Im sure even under LN2 and volt modded those things wont break 350W each. Under stock or water cooling I wouldnt imagine more than 300W really.

You can run your setup and overclock everything under air/water with a quality 1KW PSU (Corsair HX1000 comes to mind).

SYSTEM wattage, the whole entire SYSTEM. And thats with the card overclocked as well.

Memory, SSD's, and fans arent going to eclipse 50W and thats being VERY liberal on that estimate considering the SSD and ram wont break 15W (even 6 sticks overclocked).

If you already have that quality 1250w you're golden

nice gentlemen, NICE! I even posted asking that question but never got a response from that site...

I ordered the silverstone but it'll go right back, heck with the Enermax I'm future-proof for a good margin still! I've also already "modded" one of the included PSU cables due to length constraints so I would've had to eat that cost but now, no worries.

So is it a concensus that I'll have pleanty of head room with 1250W and my setup to at least hit my OC targets if not surpass them...?

Thanks again and I can't wait to fire this beast up, hopefully thing I learn along the way will turn into things I can feed back into this community as I learn as well.

Plenty of headroom my guess would be you could hit 800w draw
