Diablotek PHD Series - 2nd Generation PHD650 650W Power Supply

Comment:
Haven't had any problems with this power supply, runs quiet n' cool. As far as the guy a couple posts below me goes with the i7, you should really check your wattage requirements before buying a power supply. That specific graphics card needs A LOT of power and it's not the only component either. Have to take into consideration Mobo, Hard Drive(s), Optical Drive(s) etc.

This is a nice PS so far. It's quiet to my standards. You can hear it from 5 feet away but it sounds no louder than when your 2 feet away. A cats puring is like 2 or 3 times louder. this power suply has a bush of wires which got annoying. I say the cooling is really nice. I wouldnt hesitate to buy this.

Got it installed fine, tried to turn it one and bam... sparked and died. I wouldn't recommend this psu.

I normally do NOT write review for anything. I had to write this one though, for I had to replace it immediately with a Sigma 850W. I have an Intel Core i7 920 chip, 12GB triple chanel RAM, and a GeForce9800GTX+ video card. It ran really hot , and had a whining high pitch noise. I got 5 holes of TW 2008 in before the whole system shut down due to the excessive heat I put in my older Geforce8600 and the noise subsided, and it ran cooler, but the noise was still there, especially during TW or even mouse movement. This PS might be ok in older systems, but if you're running a powered Graphics board DON'T buy this unit. And if you really want it let me know I'll sell you mine at half price!

After having power supply failures in several of our home computers, I decided to get a power unit that was bigger than I needed (for a run-of-the-mill computer). The DiabloTek PHD650 was neither cheapest nor biggest, but its cable variety suited my needs. It's noticeably quieter and does the job, and the mesh cable jacketing is nice (but will eventually gather dust). TigerDirect's delivery was, as usual, very fast.

Good price and fast shipping. Replaced a 230W power supply in a Gateway 830GM XP Media Center desktop. This supply was about 1/2'' deeper (back to front of pc, in length but fit fine, screw holes line up perfectly. Removed left side cover of pc. Removed plastic fan shroud over processor (depress 4 small plastic tabs on bottom edge by screws, pops right off). Removed two screws to slide forward out of case about 2'' the lower DVD/CD drive and there is plenty of room to safely remove old and install this new slightly longer supply. Route supply cables tight against supply out over motherboard and DVD drive slips back into place. New PS Fan sounds SLIGHTLY louder when loading down this 650W supply.
