BoPC has posted an OCZ Modstream 520 Review
The OCZ Modstream is impressive, it's silent, and it performs great.. I tell you, it's a lot more stable than other powersupplies I reviewed, ones that were suppose to be silent.... and it's fairly cheap too (82euros for the 450watts version, and 111 for the 520watts version)! The only small problem I had with this powersupply was a high pitched noise coming from the inside. Now it wasn't really that annoying, but still worth mentioning. Put it in your case and the sound is nearly gone!OCZ Modstream 520 Review
