Any problem with replacing a 350W with a 400W or vice versa?

Replacing a 350W supply with a 400W supply is fine. It will give you spare power capacity. This could be useful if want to install additional cards into your PC. The only issue you need to concern yourself with is whether the power supply fits into the case and if it has the output cables you require for your machine. I installed this in an 8-year old Dell Dimension 8400. It fit perfectly into the case. Alignment with the existing screw holes, fan grill, and AC power plug cut-out were perfect. In my machine, I used it to provide power to the CPU, motherboard, two optical drives, a floppy drive, and two SATA hard drives. There were still unused cables available. You can download the manual from the startech.com web site. It contains a complete list of the power cables available. The cable harnesses are longer than those that came with the original power supply. There was plenty of room in my machine but I had to be careful to fold the cables into a spot that wouldn't get squished when I closed the case. It might be risky to replace a 400W supply with a 350W supply. It all depends on how much of the capacity of the existing 400W supply is being used. If more than 350W then a new 350W supply might not be able to supply the power required by your machine.

I think you need to keep the same wattage by what the computer uses. I don't think that there would a problem going higher on the wattage, hopefully not too high. That's the best that I can tell you

No problems, just remove the board attachments and plug in the new one. Still working great after two years.

If you have more than one or two internal hard-drives you might want to go with the bigger wattage. I have a home server that I loaded up too many drives and the overloaded the power supply to the point it wouldn't boot.

350w can be replaced with a 400w but would not recommend replacing a 400w with a 350w.

I am actually using a 300w PSU and everything works just fine for the past week (i7-4770, 8G ram, two HDs). But don't try to take my word and keep a 300w psu for long bc it's supposed to be dangerous to your equipment. I've ordered a 500W PSU and will replace as soon as it arrives.

I have been running 35w and have had a couple of the sockets burn up but I installed ten and had the issue with 2. Not sure they would handle 50w

Definitely not. In fact, I started out with a 400W PS, if I recall correctly, when it just had the onboard video, added a separate viceo card, and then several months later had to upgrade to a 500W PS because the system just kept conking out because it couldn't handle the load with 400W.

I think not, 500w is the less you need to use it, with a 600w maybe you can

400 watt or greater is the recommendation for this model. You should calculate how your psu is destrobuting it's power to make sure you can delegate enough to the card

If you are going to go with 500w or 450w, make sure it is a high grade power supply, and not a cheap off-brand model

300W If you upgrade the video card, be sure to change the power supply too!

Mine is in a Dell that had a 300w that went bad. I replaced with a 600w and have had no issues. When I did research before I bought the card, the suggestions that I read were a 400-500w psu

My wife has been using it for 270W and there has not been a problem. Since it's rated 300W you may be able to use it, check with the manufacturer.

I have a 400 watt power supply and it works fine.I would try it with the 250w because you can always send it back.

My read of the customer reviews supports the notion that the 255W is a terrific unit. Thanks for your reply.

I'm using 850W one for cross fire. I think 450W would be fine for single card, but it depends on your other hardwares.

Tim, from what I have read, the s3507c comes with a 160W power supply. So upgrading to 250W should not be a problem. Another option is to use a power supply recommended for that model machine ... such as: - http://www.replacepowersupply.com/rpsu-200-hp-s3507c.html (200W) - http://www.newegg.com/Product/Product.aspx?Item=9SIA3SD1DK9956 (220W) Before ordering the 250W, look at all the connectors on your current PSU and review the specifications for the 250W PSU to ensure you will have sufficient connectors for all components.

Most likely not, you simply wouldn't have enough current available. I wouldn't use anything less than a 750 W

I think you might be pushing it with a 400W PSU. I guess it depends on the item quality. You may be just fine. Not really an answer, sorry.

You should be ok running the polisher with this. This is a pure sine wave converter so it will be better for the tool anyway (versus those el cheapo converter).That said, I would NOT try to run it long with the 400W. It'd be better with 800W unit. Both this unit and the polisher has the overload protection so if forsome reason the load is exceeded either (or both) will shut off. Keep an eye on the Wagan to make sure it's not getting too hot. I'd run it for 30mins or so then wait rather than running for like 2 hours with 4.5A load.
