Can This DELL Precision PSU run a Six Core CPU

[Collider]

Got a Dell Precision T3500 with a 525W PSU and want to know if I can safely run X5650 as an upgrade.

Currently the PC is running a Xeon W3503 its only a 2 core / 2 thread but it's a 45nm Nahalem chip which is rated at 130W:

X5650 is 6 core / 12 threads, 32nm based and is rated at 95W:

Based on this reasoning I feel it should be safe swap CPU and to run X5650 (upgrading from a dual core) and should actually reduce PSU load.

The pc has 1ssd, 2hdds, and a basic GPU - lets just assume it consumes 35-50W.

Once upgraded I aim to run the pc 24/7 under constant load as a server.

Can anyone confirm if my reasoning / assumptions are correct that the current 525W PSU will safely run a six core x5650?

Thanks.

I ran the same T3500 with a W3530 and two HD5770s running full out 24/7 doing compute and the PSU didn't have any issues. I can't see why you'd have any issue with that swap for Westmere, especially since you can't OC it.

Thanks. Knowing DELL it's possible that another PSU configuration was used. You wouldn't happen to be able to check label on the PSU for how many watts it was rated for ?

I did a few of those, converting T3500 quad core to hexcores. They all had 525 watt power supplies and all are still plugging along just fine.. Mostly X5650's and one X5670. Cheap easy upgrade for the old Dells..

It's the same 525W model with 18A on the primary CPU rail. I think it's standard on all the T3500 workstations.
